The United Nations is appealing for more than $180 million next year to help refugees from Sudan's Darfur region who have fled to neighboring Chad.
The U.N. Office for the Coordination of Humanitarian Affairs says that is a 10 percent increase over this year's budget.
It says the money will be used to provide both refugees and the local population with food and water as well as basic services such as health and education.
The United Nations estimates 200,000 Sudanese have fled to eastern Chad to escape attacks by pro-government Arab militia.
It says the large influx has led to growing tensions between the refugees and the local Chadian population, as the two groups increasingly compete for scarce food, water and land.
